The orientation of actin and myosin in stress fibers present in nonmuscle cells. Introduction: Stress fibers present in nonmuscle cells are contractile in nature and are composed of actin and myosin II. Myosin II is a major component for the contraction of stress fibers in nonmuscle cells. Myosin fibers are ATP dependent and hydrolysis of ATP can bring a significant change in the conformation of myosin fibers resulting in the movement of actin filaments.

TRUE OR FALSE 1. Synthesis of the collagen primes the formation of skeletal tissues?

IDENTIFICATION. One of the B-complex vitamins which is the precursor of Nicotinamide in the coenzyme NAD+. Carrier of the activated amino acids to the ribosomes for incorporation into the growing peptide chain. Molecule that attaches to myosin and actin during muscle contraction.

Contraction of both skeletal and smooth muscle requires the influx of Ca2+ into the cytoplasm. Compare and contrast the locations and functions of the molecules to which Ca2+ binds in these muscles and explain the steps that lead to cross-bridge cycling in each type. please answer me precise and relevant to the questions thanks
